Mike Donkey

Mike Donkey is a loan shark that Roger borrows $50,000 from in Steve's name when Stan tries to impress Hideki Yoshida in "Crystal Clear".

When Stan feels inadequate after seeing the Yoshida's expensive goods during a cookout at their house, he decides to buy items to impress them after Francine invites them over in turn. With all of his credit cards maxed out or taken away, he decides to open several new cards in Steve's name. However, Roger decides to help him when his cards can't cover enough goods by getting a loan from a loan shark also in Steve's name with the threat of breaking his legs if he can't pay back the money. Roger talks Stan into using their remaining funds to travel to Atlantic City and wager in the hopes that they can increase their money.

The pair actually hit it big, but Roger spends a substantial amount of the funds on a giant crystal, unaware that Mike has his son, Mike Donkey, Jr., watching Steve's every move. Stan and Roger are late arriving home, and find the loan shark and his goons already waiting on them where they reject taking Roger's giant crystal and proceed to break Steve's legs as promised. After having done so, they are satisfied that they have met the terms of their agreement and leave.
